Answer:
It takes $350 14 years to reach $700 with a semiannual interest rate of 2.5%.
Step-by-step explanation:
Giving the following information:
Initial deposit (PV)= $350
Interest rate (r)= 0.05/2= 0.025
Number of perids (n)= ?
Future Value (FV)= $700
<u>To calculate the time required to reach the objective, we need to use the following formula:</u>
<u></u>
n= ln(FV/PV) / ln(1+r)
n= ln(700/350) / ln (1.025)
n= 28.07
28.07/2= 14
It takes $350 14 years to reach $700 with a semiannual interest rate of 2.5%.
Answer:
She bought .9 ton of compost.
Step-by-step explanation:
Take the amount of bags she bought and multiply it by the weight of each bag.
40*50=2,000
Then divide it by the amount a ton is.
2,000/2,204=0.90718474
Round it to the nearest tenth.
=.9
Then that's you're answer.
Answer:
Step-by-step explanation:
Driving 55mph for two hours, he would travel 110 miles
Driving 70mph for one hour, he would travel 70 miles.
Driving 50mph for two hours, he would travel 100 miles.
Total Distance would be 280 miles.
Average speed would be (55+70+50)/3 = 58mph
If he drove 280 miles at 70mph, it would take 4 hours
Distance = Rate X Time
Answer:
128mm^2
Step-by-step explanation:
Surface area of a triangular prism formula: bh+(S1+S2+S3)h
base= 8
height= 5
side 1 =5.8
side 2= 5.8
side 3= 6
8*5+(5.8+5.8+6)5
40+(17.6)5
40+88=128
128 mm
hope this helps!
